An extremely precise timekeeping device regulated in correspondence with a characteristic invariant frequency of an atomic or molecular system. Submit your e-mail address below. The clocks are compared using GPS signals and two-way satellite time and frequency transfer. In a pendulum-driven clock, for example, the oscillation is the back and forth movement of the pendulum (the In 1945, Isidor Rabi, a physics professor at Columbia University, proposed that atomic vibrations could be used to keep time, based on something he'd developed called atomic beam magnetic resonance. n 1. atomic clock synonyms, atomic clock pronunciation, atomic clock translation, English dictionary definition of atomic clock. Four years later, the National Bureau of Standards (now the The first commercial cesium-based atomic clocks were manufactured by the National Company, a Massachusetts-based firm; Frequency Electronics, FTS, and Hewlett-Packard ( Reputation management is the practice of attempting to shape public perception of a person or organization by influencing online information about that entity.Risk assessment is the identification of hazards that could negatively impact an organization's ability to conduct business.The Payment Card Industry Data Security Standard (PCI DSS) is a widely accepted set of policies and procedures intended to ...Risk management is the process of identifying, assessing and controlling threats to an organization's capital and earnings.PCI DSS 12 requirements is a set of security controls that businesses are required to implement to protect credit card data and ...The Federal Information Security Management Act (FISMA) is United States legislation that defines a comprehensive framework to ...A vulnerability assessment is the process of defining, identifying, classifying and prioritizing vulnerabilities in computer ...Telemedicine is the remote delivery of healthcare services, such as health assessments or consultations, over the ...Project Nightingale is a controversial partnership between Google and Ascension, the second largest health system in the United ...Medical practice management (MPM) software is a collection of computerized services used by healthcare professionals and ...Disaster recovery as a service (DRaaS) is the replication and hosting of physical or virtual servers by a third party to provide ...Cloud disaster recovery (cloud DR) is a combination of strategies and services intended to back up data, applications and other ...A crisis management plan (CMP) outlines how to respond to a critical situation that would negatively affect an organization's ...Hot plugging is the addition of a component to a running computer system without significant interruption to the operation of the...An M.2 SSD is a solid-state drive (SSD) that conforms to a computer industry specification and is used in internally mounted ...A kilobyte (KB or Kbyte) is a unit of measurement for computer memory or data storage used by mathematics and computer science ...Just reading the English translation of Einstein's article on "On the electrodynamics of moving bodies" and noticed a comment in Section 5 - "7 Not a pendulum-clock, which is physically a system to which the Earth belongs.

"What this means is, we can make sure there is only one atom per cell in our In short, the field of quantum research developed with NIST researchers working with atoms in a certain way that would improve the precision of To demonstrate their method, the researchers began with a type of Much as a grandfather clock depends on the swinging of a pendulum, his prototype The tests demonstrate for the first time that these types of "optical Atomic clocks synonyms, Atomic clocks pronunciation, Atomic clocks translation, English dictionary definition of Atomic clocks. The majority of the clocks involved are caesium clocks; the International System of Units (SI) definition of the second is based on caesium. The standard kind of atomic clock, which is based on the vibrations of cesium atoms, gains or loses less than one second in three million years. An atomic clock is a clock that uses an electronic transition frequency in the microwave, optical, or ultraviolet region [2] of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Definition of atomic clock written for English Language Learners from the Merriam-Webster Learner's Dictionary with audio pronunciations, usage examples, and count/noncount noun labels. An atomic clock is the most accurate type of timepiece in the world, designed to measure time according to vibrations within atoms. An extremely precise clock whose rate is controlled by the vibration of particular atoms or molecules whose frequency does not change.
